HANDLE-WHEEL FOR VALVES.

SPECIFICATION forming part of Letters Patent No. 716,761, dated December 23, 1902. Application filed May 17, 1902. Serial No. 107,851. (No model.)

To all whom, it may concern."

Be it known that I, GEORGE M. Rrromn, a citizen of the UnitedStates, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have inventednew and useful Improvements in Hand-\Vheels for Valves, of which the following is a specification.

This invention relates to hand-wheels for valves, and more particularly designed for use on hot-water and steam valves.

The object of the invention is to provide a handle which will be a non-conductor of heat and will remain cool at all times irrespective of the temperature of the pipes in which the valve is located.

With this object in view the invention consists in the peculiar arrangement of parts and combination of parts to be described hereinafter and illustrated in the accompanying drawings, in which Figure l is a top plan view of a complete valve-handle. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a vertical cross-sectional view of the valve-handle complete. Fig. I is a plan view of one of the flanged disks. Fig. 5 is a plan view of the intermediate disk, and Fig.6 is a side elevation of the coil surrounding the disks.

In carrying out the invention I provide a disk 1 of suitable diameter, on the periphery of which is arranged a plurality of fingers 2,

spaced apart and between which are fastened the convolutes of a coil-spring, to be referred to hereinafter. The reference-numeral 3 designates a projection arranged on the periphery of the disk 1 and is provided with an opening 4, through which is inserted a strand of coiled wire 5. This wire is constructed after the manner of a coil-spring, and the convolutes are interposed between the fingers 2, the spring being bent to conform to the contour of the disk 1, the ends beinginserted in the opening 4E of the projection 3. The edges of the fingers are spread slightly to embrace the strand and tightly lock the convolutes in engagement with the disk 1. Arranged on either side of the disk 1 and riveted thereto are flanged disks 6 and 7, which are provided with outwardly-projectingcurved edge flanges S to embrace a portion of the sides of the convolutcs of the spring to prevent any lateral displacement thereof from the disk 1 and also to permit the convolutes to be seated. After the device has been formed thus an angular opening 9 may be formed to admit the end of the valve-stem. Owing to the peculiar form thus provided it will be impossible for the wheel to become heated, even though an excessive temperature be provided within the pipes.

While I have specifically described what to me at this time appears to be the very best means of accomplishing the desired result, I would have it understood that I do not limit myself to the exact details of construction shown, but reserve the right to make such slight changes and alterations as may suggest themselves from time to time without departing from the spirit of this invention and sacrificing any of theadvantagesthereoi.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patout, is-

l. A valve-handle comprising a disk on the periphery of which are fingers,1 a coil surrounding the disk and engaged by the fingers, and flanged disks secured to either side of the first-named disk and bearing against the respective sides of the coil.

2. A valve-handle, comprising a disk, fingers on the periphery of the disk and spaced apart, a coil the convolutes of which are adapted to be spread and engaged by the fingers so as to lock them in engagement with the disk and means for clamping the sides of the coil to the disk.
